“最近几年中”可以翻译为“in recent years” 或者 “over the past few years” 。
“in recent years” 强调在近期的这几年时间段内，是比较常用且简洁的表达。例如：In recent years, there has been a significant increase in online shopping.（最近几年中，网购数量有了显著增长。 ）
“over the past few years” 同样表达在过去的这几年里，更突出从过去到现在这一段持续的时间跨度。例如：Over the past few years, our company has expanded its business to many countries.（最近几年中，我们公司已经将业务拓展到了许多国家。 ）
